VVSPECIFICATION forming part of Letters Patent to; 279,720, dated June ,19, 1883.

Application filed May 24, 1882. (No mom-1.!"

To all whom itmay concern.- Be it known that 1, WILLIAM L. Cnowson, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented a certain new and useful Improvement in CombinedCleanei-s and Feeders for Cotton-Girls, of which the following is a full, clear, and exact description, ref eren'cebeing had to the accompanying draw- 1 ings, forming part of this specification.

The present invention relatesto the class of cleaners and feeders for, cotton-gins exemplified in my Patent No. 237,255, granted February 1, 1881; and it consists in the construc- 15 tion and combination of devices hereinafter described and claimed. V I .lntheidrawings, Figure 1. is a side elevation-g fthe machine. Fig. 2 is a plan view, of the cad-rake with stopping mechanism'at- 2o tach'ed. Fig. 3 is an elevation of the feed-rake with stopping mechanism attached. Fig. iis

,anelevation of the side of the machine oppomite-to .that shown in Fig. 1.. Fig. 5 is an end wriew of the lower part of themachine, show g rug the position of fan and traps at each side.

. iig; 6 is'a longitudinal section of the machine. I lrig, 7 is a plan of the roller-carrying and giviug motion to the feed-apron. Fig. 8 is alougitudinal section, showing the construction of d the'ibeater. Figs. 9 and 10 are detail sectional views of the feed-apron having the slats ar? ranged thereon so as to form seed-cells. The case and framcare shown at A A.

B is the cotton-box, the bottom of which consists of an endless apron, B, supported by driving-roll O and a stretching-roll, G.

These rolls are journaled in a shoe or frame, B", j which is fitted into the bottom of the cottonbox in an adjustable manner, for the object 46 hereinafter stated.

' The two side views, Figs. 1 and 4, illustrate the gearing and banding of the wheels for giving motion to the several parts of the machinery.

p D is the main belt, and its passage over pulleys d d d causes the rotation of the heaters '11) D I): The belt E from the opposite end of the beater D drives the pulley E,- as shown in Fig. 4, giving motion to the oscillating rake,

50 and the belt E, (also shown in Fig. 4,) carried around pulleys c (2 cf c gives motion to fourth surplus cotton.

which said pulley is keyed. The endless apron B derives motion from the pulley H on the rake-shaft, transmitted through t-hebelt H, pulley H, pinion 71 cog-wheel'l, pinion 2', and small idlepinionj to the pinion 7; on the shaft of the driving-roll C, so as to give the required direction and speed. 4 I.will now describe the oscillating rake and the mode of operating the same.

The headofthe rake consists of uprightoscillating bars R R, with horizontal connecting-bars It" RTunning transversely to the maohine. The upright bars R are slot-ted, as shown at r, toallow'the passage .of the bar L, which forms the axis of oscillation. The said upright bars Rf are, supported by a second transverse bar, M, passing loosely. through them, and fixed-at its ends to erank-arn'is M, carried by the shafts of the pulleys E and H.

The revolution. of the crank-arms M gives to the lower ends of the uprights an oscillation of greater amplitude than that of the crank it sell. The construction and operation are such thatthc teeth 1' in their oscillation descend to within a short distance of the roller 0, and, moving baclcwardly therefrom, carry back any The continued oscillation carri es the teeth upward and backward, releasing the cotton from the teeth, and in the upper movementthe teeth are carried foriyardto the place of beginning, ready to againjth row back any surplus cotton.

To regulate the space betweenfthe end of the feed-apron B and the oscillating rake, the,

vframe B", in which said apron is mounted, hav

ing its fulcrunrpoint at If, is raised or lowered by means of the lever N, working at its upper end in segment 0, and secured by thumb-screw n. The lower end of lever hl is keyed to a shaft, N, carrying cams I, which work on the under side of the adjustable apron-frame, and by the motion of the lever is made to raise or depress said frame, thus lessening or increas ing the space between theend oi the feed-apron and the rake. It will be seen that the more elevated the end of the feed-apron is relatively to the rake the less cottoinwill pass through, and vice versa.

The i'eedapron B is composed of a suitable belt and slats rabbeted, as shownjn Fig. 10, or arranged, as shown in Fig. 9, so as to form beater, D, and to the fan F, on the shaitf of l ribs and cells, the object of which is to allow the contents Thereof,

space in which the seed may lie and be hehl, so that the rake, while separaiing: the-remain: and throwing back thesnrplns, will no? be able in its backward movemeni {'0 lriv'e the seed all back.

The direeiion 01'' motion of lhe several par-is of the machine and the path of the cotton are indicated by feathered arrows and rho air-enr rent by featherless arrows. The cotton, after passing along n'ith the feed-apron and being raked over by the oscillating rake, is then, by the suction of the fan, iii-awn onto and under the beater l), revolving iorward, next over and onto the beater D moving in a ermtrary direction, then to the third bearer, l), and ihe fourth beater, D revolving in same direction as the first beater, ihen over flanged roller (,2 into the gin below. By the opening at 'l the seedand heavy foreign maflers-sneh as nails, &r.-iall ontin the direetion indicated by the arrow i. A door, T, hinged to The easing so as to move in an inward direelion, serves as a medium for varying; the size of this opening, an is seen in .i ig. (i. A slotted brace and setsorew are generall y em ployeil for retaining the door l" in any position in which it may be placed. Through the screen S, beneath i he boaters, all (lost is drawn oni by the snotion of the fan E. The/opening U in the easing ofihe tan permits access to the fan chamber for cleaning purposes, and chambers 2 at the sides of said. iinrensing receive the rlir or rei'n'se matter whieh drops through the SereenS 3, these chambers being snfiieientlylarge to per mil workmen to enter the same for removing 'ihe openings r above the ,beaiers are for the purpose of regulating the current of ai r to the notion while being agital ell by the heaters. This air passes through the cotton and through the screen re the fan, and in its passage it carries with it (lust and snrh leaf or trash as will pass thronglr ghe meshes of he sereen, and by the fan ii exlhese openings are provided with slides V to open and close the name, so that the amount ol'air nassmllhrongh can boregn lal'erl, ihegrarle of notion :ielermini .gihe force or volume oi'air-blast' whieh is necessary.

l l l l Themeohine is i'hrown in and out of gear by the movement oi lhe lever W, which arts on a clutch, X, and bythe spiral spring- .1- is kept in posfaiiionwhile working. To throw out of gear, the lever is pressed inward against the sirie, and by means of a eord fastened to the end oil'he lever and passing through eyes and down through the floor the starting and stop ping are placed under control of the ginner below.

Having thus described my invention, the followingis What I claim as new therein and desire to secure by Let'rers Patent:

1. In a eoi'toirgin feeder, the combination of the vertically-adjustable traveling i'eech apron lniving slats or ribs arranged to form seed-cells, the oscillating rake arranged at the upper or discharge end ofsaid apron, and the cot-ton box or receiver having a discharge opening or chute located at the upper end of said ieedapron, with a beater-chamber, beaters, and suntionian, substantially as and for the purpose set forth.

2. In a eoti'on-gin feeder, the combination of the eottoirbox B, having opening; T and adjustable shutter T, with the traveling feedapron i'erminating near said opening, as and for the purpose set forth.

3. In a cotton-gin feeder, the combination of the series of bearers, a easing inclosing said boaters, theverfieally-ailjustable frame, a feedapron mounted on said frame over the beatereasing', and the delivery regulator or rake arranged above the said apron, as and for the purpose set forth.

L. In a cotton-gin feeder, the combination of the trans erse ba-r M, crank-arms M, pulleys ii and H, and their shafis, clutch X, and lever XV, wi oh the slotted arms R, rake-head; r, eonneeting-bars R and transverse as and for the purpose set iorfh.
